“At around 10 am, the man identified as Alok Mitra jumped onto the tracks as the Dum Dum-bound train was entering the station. He didn’t come under the wheels of the train but came in contact with the third rail and was rushed to the Calcutta Medical College and Hospital in a serious condition,” they said.

However, he was declared brought dead by doctors at the hospital.

Metro Railway services were suspended for around 30 minutes due to the incident, the sources added.
